Abstract

The phase changes and chemical reaction of phthalazine was investigated at pressures <2.5 GPa and temperatures <300 ℃ to discuss behavior of nitrogen in sedimentary organic compounds in subducting slab. A phase change to high-pressure phase was observed at 0.4 GPa, 22℃. A distinct decrease of remaining phthalazine was observed in the samples recovered from the conditions above 250-275℃ at <1.5 GPa. Formation of decomposed and polymerized products with a decreasing N/C ratio indicate that nitrogen atoms in the aromatic ring induced decomposition of the molecule.
